Multiple-object ghost imaging with a single-pixel detector

摘要

Ghost imaging has become increasingly popular in quantum and optical application fields. In this work, we describe a multiple-object ghost imaging arrangement based on the computational framework. In this configuration, all the wavefronts of the object beams respectively interacting with the targets are collected together by only a single-pixel (bucket) detector, but any one of these objects can be ghostly imaged from the recorded data independently. The crosstalk noise and signal-to-noise ratios of the ghost images, which vary with the number of the objects to be imaged and of measurements, are theoretically analyzed and the results are presented by computer simulations.
